There’s been a beautifully cast movie and a card game, as well as various other merch I haven’t kept track of. But it boils down to the books, which were re-released in color hardcovers (coloring by Nathan Fairbairn) beginning in 2012. Now, to celebrate the anniversary, Oni will be putting out omnibus versions. The six books will be collected in three softcovers, available individually at $29.99 each, or in a boxed set ($89.99). That sounds like a lot, but the color hardcovers were $25 each, or $150 for the six.

The new color paperbacks will be available on April 10, 2019, with these new covers.
